Pin 8 is Request to Send/Ready for Receiving which means RTS or DSR . Do you have any system design with such functionality using 8 line for modems connections. As i have seen on other blogs RI and DSR is merged as RI is used for dial up modems alone.

    Hi Anusha,

    RI and DSR generally have different functions, so it isn't clear to me how they could be merged. If you do not plan to connect to a dial-up modem, it may make sense to just leave RI disconnected instead since there will be no need for ring indication. (Even if a dial-up modem is used, you may be able to avoid using RI and instead use the other data lines to communicate the modem status to your DTE.)

    I may be misunderstanding your question, though - if so, please let me know.

    Regards,
    Max
